This course teaches how to design a feedback system to control a switching converter. The equivalent circuit models derived in the previous courses are extended to model small-signal ac variations. These models are then solved, to find the important transfer functions of the converter and its regulator system. Finally, the feedback loop is modeled, analyzed, and designed to meet requirements such as output regulation, bandwidth and transient response, and rejection of disturbances.
Upon completion of this course, you will be able to design and analyze the feedback systems of switching regulators.
This course assumes prior completion of courses Introduction to Power Electronics and Converter Circuits.

From the lesson

Ch 7: AC Equivalent Circuit Modeling

How to extend the converter steady-state equivalent circuits, derived in the previous courses, to obtain small-signal ac equivalent circuits that model the important converter and regulator system dynamics.
